The document discusses indirect object pronouns in Spanish. It explains that an indirect object answers the questions "to whom?" or "for whom?" and receives the direct object. Common indirect object pronouns are me, te, le, nos, les. The pronoun replaces the indirect object of a verb. Indirect object pronouns usually come before the conjugated verb. Le and les can be ambiguous so a prepositional phrase is often needed for clarity. Indirect object pronouns can also be used with se to talk about unintentional events.
